Ōhau Beach is an unpatrolled west coast beach, so swimming requires caution and good judgment. While it's tagged as family-friendly, this refers more to the quiet community atmosphere than ideal swimming conditions. The beach can experience surf, currents, and rips, particularly near the Ōhau River mouth. On calm days with settled conditions, paddling and supervised play in shallow water may be suitable for families. Always supervise children closely, avoid the river mouth area where currents are stronger, and never swim alone. Beach walking, picnicking, and exploring are safer family activities here than swimming.

Ōhau Beach is best enjoyed during settled weather conditions, typically more common in summer months (December-February), though the beach remains accessible year-round. The less-crowded nature means even summer visits feel peaceful and relaxed. Sunset viewing is exceptional throughout the year, with the west coast position offering beautiful evening skies. Spring and autumn provide comfortable temperatures for beach activities without peak-season visitors. Winter can be atmospheric but windier and cooler. For families, warmer months offer better conditions for beach play and exploration. Check weather forecasts before visiting as conditions can change rapidly on the west coast.

Ōhau Beach is located beside the Ōhau River mouth in southern Horowhenua, approximately 45 kilometres southwest of Palmerston North. From State Highway 1, turn west at Ōhau township (between Levin and Foxton) and follow Ōhau Beach Road approximately 7 kilometres to the coast. The road is sealed and clearly marked. From Levin, it's about a 20-minute drive south and west. Parking is available near beach access points in the small settlement. No public transport services this area, so a private vehicle is necessary. The rural drive offers views of farmland before reaching the coastal community.

Ōhau Beach is a small coastal community with basic facilities. Accommodation options are limited, consisting primarily of private holiday homes and baches available for rent. There may be a motor camp in the area offering camping and cabin options. The settlement has minimal commercial development—no restaurants or cafes on the beach itself. Visitors should bring food and supplies from Levin or Foxton, which have supermarkets and services. Public toilets and basic amenities may be available near beach access areas. The simplicity is part of the appeal for those seeking a quiet, uncommercialised beach retreat.

Ōhau Beach's position beside the Ōhau River mouth creates a distinctive coastal environment where freshwater meets the Tasman Sea. This small community beach offers an intimate, local atmosphere that's particularly appealing for visitors seeking quieter alternatives to busier regional beaches. The beach serves as useful coverage for southern Horowhenua exploration, being slightly less known than its neighbours. The settlement maintains a traditional New Zealand beach community character without modern tourist development. Sunset views are particularly beautiful, and the sense of space and tranquility makes it ideal for those wanting to experience authentic Kiwi coastal life away from commercial beach destinations.
